Architect and Engineer’s Specifications: NS26-300+ Network Switch The network switch shall provide twenty-six 10/100/1000 Mbps half/full duplex ports on RJ45 connections. Twenty-four of the 10/100/1000 Mbps ports also provide IEEE 802.3at compliant PoE+ with up to 300 Watts total power budget. Additionally, the switch shall offer four 1 Gbps SFP ports. An Out-of-Band 1 Gbps management port shall be offered along with Console ports utilizing an RS232 protocol accessible via RJ45 and USB-C connections. The network switch shall be fully Layer 2 and Layer 3 managed (non-blocking) and preconfigured with appropriate quality of service (QoS) for use with Q-SYS Q-LAN audio, video, and control networks as well as related network AV technologies including AES67 and Dante. It shall provide IGMP snooping and IGMP querying for networked audio and video multicast traffic. An inbuilt DHCP server shall be preconfigured for optional use in applications requiring automatic device addressing. The network switch shall have a maximum power consumption of 401 Watts and feature a rear panel IEC power input socket for 120-240 VAC. Operating temperature range shall be 32º to 113º F (0º to 45º C) with a maximum relative operating humidity of 90%, non-condensing, and maximum thermal output of 1369 BTU/hr. Ventilation shall be provided by thermostatic and load-controlled fans with the network switch capable of operating fanless up to 25º C ambient, less than 43º C internal, and less than 45 Watts PoE load. The network switch shall meet applicable UL/cUL/IEC/CE/RCM/CCC/GB/YD/BSMI safety requirements and comply with FCC/CE/VCCI/RCM/CCC/ISED/BSMI Class A emissions limits. The device shall be RoHS, WEEE, and REACH compliant. The full-width 1U chassis shall be constructed of cold rolled steel. The dimensions of the network switch shall be 17.32” W x 1.70” H x 10.12” D (440 mm x 43.2 mm x 257 mm) and standard 19” 1U rack mounting hardware shall be included permitting the network switch to be mounted ports forward (flush), ports forward (recessed), or ports rearward. Additionally, a front panel M10 threaded hole shall be provided for clamp mounting plus four M5 threaded holes on the bottom for 50x100 mm VESA plate mounting. The network switch shall be the QSC Q-SYS NS26-300+ Network Switch.
